I’m Don — a solo developer, theorist, futurist, and occasional mad scientist in the best possible way. I build tools, models, and experiments that help people understand and shape the systems around them. I don’t come from a traditional engineering or academic background; everything I know comes from curiosity, iteration, and refusing to accept “that’s just how it works.”
I don’t claim to be a researcher. I explore ideas, test them, break them, rebuild them, and see what survives. My work spans software, theory, and practical problem‑solving. If something can be made clearer, faster, or more humane, I try to build it.
I’m Don. I love to build things, ask "why?", and solve problems. I'm not a traditional engineer or professor—I'm self-taught and driven by curiosity. I like to take apart complicated ideas and put them back together in a way that makes more sense.
I basically spend my time building tools and coming up with new ideas to see if they actually work in the real world.
The ideas on this site are mine — but the process behind them is collaborative. I work with AI tools constantly, not as a replacement for thinking, but as a way to iterate faster, test assumptions, refine concepts, and debug the parts I can’t code myself. I can read code well enough to reason about it, but I don’t write it from scratch.
My workflow is a mix of deep‑dive clarity and rapid prototyping. When something grabs my attention, I can map it out with obsessive detail. Other times, I move fast, build the thing, and clean it up later. It’s not linear. It’s not always pretty. But it moves the work forward.
All the ideas here are mine, but I use AI to help me build them faster. I'm good at the logic and the "big picture," and I use AI as a high-speed assistant to handle the coding and technical details.
I work in two modes: sometimes I dive deep into every tiny detail, and other times I move as fast as I can just to see if a prototype works. It's a bit messy, but it gets the job done!
Semsey Technologies is the umbrella for everything I create:
Everything I build follows the same principles: modular, predictable, privacy‑respecting, and empowering for the user.
I make a lot of different things, but they all fit into these categories:
My goal is always to give you more control and keep your private stuff private.
Most systems — technical or human — are harder to understand than they need to be. They hide their logic, bury their settings, and assume the user should adapt to the system instead of the other way around.
I build the opposite.
My goal is to create tools and models that:
Most things in life (like apps or government rules) are way more confusing than they need to be. It feels like they're designed to keep you in the dark.
I want to fix that.
I build things that:
Nothing on this site is presented as gospel. These are theories, ideas, and frameworks — starting points, not final answers. Some of them I fully believe in. Some of them I’m still unsure about. Some of them I may not even agree with later.
I try to stay objective, but like everyone else, I have blind spots and biases I can’t completely escape. That’s part of the process.
My goal isn’t to convince anyone that I’m the smartest person in the room or that I have every skill known to man. My goal is simple: if something here adds value to your thinking or your work, then it’s worth sharing.
Take what’s useful. Ignore what isn’t. Remix anything you want.
I don't have all the answers. The things on this site are ideas I'm exploring—not "facts" that can't be questioned. I might even change my mind about some of this later!
I try to be fair, but I'm human and I have my own way of looking at things.
I'm not trying to show off. I just want to share what I've learned in case it helps you too. If an idea here helps you, awesome. If not, don't worry about it.
To keep this project sustainable and free, I use a decentralized infrastructure. Instead of expensive hosting, I rely on a mix of services:
The source code for this entire website and my primary projects is public. Anyone can audit it, learn from it, or build on it.
I use free services like GitHub, YouTube, Supabase, and Google Drive to keep this site running without needing a big budget. This lets me keep everything free for you to use.
Everything I've built is open. You can look at the "blueprints" (the source code) anytime you want to see how it works.
If you want to explore an idea, ask a question, or build something together, I’m always open to conversations that lead somewhere interesting.
If you want to talk about an idea or build something with me, I'd love to hear from you. Let's make something cool!
